TDI remap to 165bhp???!!

[charlie123ii]

ive got a 115bhp tdi and contacted CELTIC TUNING about their £300 remap with some extraordinary results, they reckon they can push 165bhp from my little iddy biddy turbo just with a remap?? anyone heard of that much before??[:D]

[Bundles]

Yup, and they can chip the 140bhp 2 litres to 220bhp according to some places [:)]

Although they were restricted to 140bhp for a reason, VW couldn't economicaly build a gearbox strong enough to handle the torque.

[Stu]

You'd probably need to think about an uprated clutch as the torque increase will be even more than the bhp increase! My brother in law recently had his PD110 remapped, not sure on the power/torque but it's quite an increase and the (admittedly high mileage) clutch isn't very happy! [:P]

[Seraph]

hmm, like to see that in practice...
as i would 165 from 115hp.

You'd probably need to think about an uprated clutch as the torque increase will be even more than the bhp
and the brakes too!

[Phil.]

It can be done, fella I know has a MK5 105bhp diesel mapped to 165. My Mk2 8v is just slightly quicker out of the stalls but once into 4th gear he reels me in.

It goes well up hills aswell.

[Seraph]

115 to 165 seems just about plausible, but 140 to 220!!

[madmk4]

The clutch should be fine, my bro i law runs a Allard tuned AMD hybrid turbo 130pd that uses the stock clutch annd its been used on track for well over a thousand mile, been to the ring and regularly towed ribs out of the water !

As for the gearbox not being strong enough...The later 6spd have hollow mainshafts to increasde the strength..Hes had no problems what the transmission whatsoever.

[Bundles]

115 to 165 seems just about plausible, but 140 to 220!!

Bear in mind that not one has ever HAD 140bhp, every one i've ever seen or heard of dyno'd has had 155-160bhp.

[Seraph]

Thats odd, because i have not heard of one person on ukmkivs saying this!

The most i can tell people have got, is the high 180s. Even with a AMD turbo upgrade, the power is estimated at 210hp.

[Matt82]

ditch the mesh out of the maf, itll feel faster still lol

when i was mucking about with my pd130, most of them were making over 130hp on uk roller. i put that down to german horses being bigger

[Crispy 8V]

seems a touch high TBH, and the 115 has the VNT15 turbo which does not like too much on upgrades, the shaft is thinner and weaker, and tends to snap[:|]

now if you had upgrade the turbo before hand I'd say go ahead, with the right intercooler

[pascal77uk]

you need a bigger turbo, intercooler and injectors to hit 220, i would have thought

[craigt1985]

revo reckon 150 from a pd115

[prof]

just don't, ask him what the cylinder pressures are and what the EGT is, seen some very scary proper test results when a major manufacturer ran a popular diesel remap on a proper test cycle. Most modern diesels are right on the edge anyway, so any more is running in "danger time"

[dubst16v]

so whos gonna buy a remapped diesel a few years down the line? [:-B] lol

[oak8vgti]

someone who hasnt been told by the seller [LOL]

[Matt82]

i did, from an auction :S

it was a 115pd that had been chipped. below 2200rpm the gearbox would judder when you dished up a the mountain of torque it had.

oil temp was about 10-15* higher than my previous 115pd too

was quick tho

[dUff]

Humm the clutch on my 2.0 TDI 16v is not really up to the job of the stock engine let alone a chipped one.

I have done 95k on this gearbox and clutch now mind ,5th syncro is on the way out and it judders up hills in low revs, mind you i do tend to slip the clutch a bit for 2nd gear pull aways etc

what torque figure are the quoting for this 165bhp remap , ?? 250 lbf ???

[Matt82]

wow. you got a lotta miles on your 2.0 tdi quickly.

mine would judder at low revs in almost all gears. sad thing is, when my sis drove it, she is mechanically unsympathetic so just floored it from low revs everywhere so it was juddering everywhere.

the new buyer didnt mind for some reason. i explained that you shouldnt floor it at low revs, just go sensible with the throttle, once over 2.2krpm though, have a ball!

[Toyotec]

what torque figure are the quoting for this 165bhp remap , ?? 250 lbf ???

This is what I was wondering myself seeing that the stock ones have 236 from 1500-3600

[Matt82]

taking the gauze out of the MAF made a great difference to my later PD130, but im not sure id go for a simple rechip after what ive seen in the past.

doing things like making sure air actually flowed through and past the intercooler made a difference too.

[Collie]

how can celtic prove this will they do you a power run pre and post remap. any way forget the numbers, if it feels significantly quicker after the remap for 300 quid thats all that matters , isnt it?

[dubst16v]

that and having a clutch and gearbox 6months later?? lol

[Matt82]

if it kills the box within 6 months then you know it packs a lot of fury

or you could just drive a bit more sensible and not hammer them at low revs/speed

[Seraph]

Humm the clutch on my 2.0 TDI 16v is not really up to the job of the stock engine let alone a chipped one.
I have done 95k on this gearbox
95k! - rep or taxi driver?!

[dUff]

its just the drive to work lol , never used this one for work purposes , did that in the VR6 was all good in pence per mile :-)

[Matt82]

thats what i thought lol what year is it?

saying that, my 2002 a4 pd130 had 104 or 114k miles when i got it in 2004 :D

[mexicorich]

Clutch problems ahve been common on chipped TDis
Many of the programs have had to be modded to reduce the torque spike at 2,000rpm because standard clutches wouldn't cope unless brand new

[prof]

No kidding guys, reported exhaust gas temps in the high 900s and cylinder pressures way way above safe limits, and it also made no where near the claimed figures. BEWARE.

[prof]

I seem to remember Trendy Tramp forcasting these problems a few years ago, and knowing about these things for him is a full time job

[dubst16v]

trouble is why are none of these companies making people properly aware of the long term effects?

[Seraph]

ahh, now theres someone you could rely on for solid, cr@p-less info [:y:]

[Matt82]

i could kill a clutch and gbox on a standard engine. if you drive it like a tard, its bound to die.

theyre hardly making freakish levels of power, but if you can feel the box isnt happy and you have an ounce of sense, you dont let it try to pull itself apart at 1500rpm do you

[prof]

trouble is why are none of these companies making people properly aware of the long term effects?


what? like Marlboro [LOL] these companies probably do not have the serious test equipment, but as a lot of the remaps don't show up on a diagnostic, and manufacturers are getting warranty claims for stuff that may have been caused by the remap, the manufacturers are getting very interested in it all

[Matt82]

thats what i thought too. i know smoking is more than likely to damage me so i do it in moderation :D

same as my golf too, i dont do full bore standing starts cos my ABF POWERPLANT OF FURY would soon destroy everything else, including itself.

[dubst16v]

not that i make a habit of it but ive got 2.0 16v mk2, standard clutch n gearbox and solid engine mounts and given her a few harsh standing starts with no problems at all.

but everything in moderation i guess

[Matt82]

you can destroy pretty much anything if you give it enough abuse. im sure it would be easier if you had a chipped tdi turning out 300lbft or more when it only left the factory with 230
